Abstract
A method for determining a shape of a shift roll for a rolling mill, includes the steps of determining a necessary control amount distribution αfor a plate crown with respect to plate widths, based on a distribution of the number of plates rolled by a target rolling mill with respect to plate widths, and providing a maximum radius difference yof the shift roll. The method further includes the steps of preliminarily determining a line yof a roll radius distribution with respect to plate widths, based on the necessary control amount distribution αand the maximum radius difference y, shifting the line yof the roll radius distribution by a maximum roll shift to obtain a distribution Δyof a roll gap change amount with respect to plate widths under the maximum roll shift, and smoothing sharp local changing part of the distribution Δyof the roll gap change amount.
